Step 1: Read the facts.
A 12-year-old boy is made to work in a fireworks factory. We must find the fundamental right that is broken.
Step 2: Recall the right against exploitation.
This part of the Constitution protects children from dangerous and exploitative work.
Step 3: Apply Article 24.
Article 24 says no child below fourteen years can be employed in a factory, mine or any hazardous job.
Step 4: Check the facts against it.
A fireworks factory uses explosives, so it is clearly hazardous, and the boy is below fourteen.
Step 5: Rule out the others.
Article 21 is life and liberty, Article 14 is equality, and Article 32 is the right to move the court. The exact violation here is child labour in a hazardous job.
Answer: Article 24 (Option 1).
